This lists the character tables for the more common molecular point groups used in the study of molecular symmetry.These tables are based on the group-theoretical treatment of the symmetry operations present in common molecules, and are useful in molecular spectroscopy and quantum chemistry.
Symmetry elements of formaldehyde. C 2 is a two-fold rotation axis. σ v and σ v ' are two non-equivalent reflection planes.. In chemistry, molecular symmetry describes the symmetry present in molecules and the classification of these molecules according to their symmetry.
A plot of triples generated by Euclid's formula maps out part of the z 2 = x 2 + y 2 cone. A constant m or n traces out part of a parabola on the cone. Euclid's formula [3] is a fundamental formula for generating Pythagorean triples given an arbitrary pair of integers m and n with m > n > 0. The formula states that the integers
The possible orbital symmetries are listed in the table below. For example, an orbital of B 1 symmetry (called a b 1 orbital with a small b since it is a one-electron function) is multiplied by -1 under the symmetry operations C 2 (rotation about the 2-fold rotation axis) and σ v '(yz) (reflection in the molecular
Thromboxane A2 Thromboxane B2. Thromboxane is a member of the family of lipids known as eicosanoids. The two major thromboxanes are thromboxane A2 and thromboxane B2. The distinguishing feature of thromboxanes is a 6-membered ether-containing ring. Thromboxane is named for its role in blood clot formation .
A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.The reactant entities are given on the left-hand side and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction.

Hemoglobin A (HbA) is the most common adult form of hemoglobin and exists as a tetramer containing two alpha subunits and two beta subunits (α2β2). [3] Each subunit contains a heme group that diatomic oxygen (O 2) molecules can bind to. [5]
